In their words
Positions and remarks grouped by topic, each with the exact quote and where it was said.
Artificial intelligence
Brunton argues that AI is ideal for low-stakes, verifiable tasks but that society needs a firewall for high-stakes decisions.
“we need a firewall of what needs to actually be verified”

Brunton argues that even if AI only recombines human knowledge, this should not be seen as derogatory, and he thinks it is more extrapolatory than that.
“I don't think we should be interpreting that as derogatory at all. I do think it is more extrapolatory than that”

Brunton argues that knowing a solution exists is a strong motivator for humans to rediscover it quickly.
“At the same time, if we found out that another country had invented teleportation or time travel, I guarantee we would reinvent it in the next five years”

AI alignment
Brunton warns that greater intelligence in AI systems does not imply greater morality.
“Like super intelligence does not imply super morality. And I think that's a huge concern with AI systems”

Navier–Stokes existence and smoothness
Brunton says the Navier-Stokes blow-up result leaves practical fluid engineering unchanged, contrasting a million-dollar math problem with a trillion-dollar engineering problem.
“you know, we solved the million dollar math problem. There's a trillion dollar engineering problem, which is like, how do you predict these things in a fast, efficient way”
